AutoCAD .NET :: Insert Block Into Another Open Drawing

I would like to be able to collect information from a drawing via a sub-form and then insert a block with attributes (populated with collected info) into another open drawing.  The insert operation would be launched from a button on my sub form.

Is this possible?

From the code below I attempted a test to simply select a point from another open drawing but was not successful.  However, once I closed both forms the target drawing file is activated.

Private Sub Button2_Click(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles Button2.Click
Me.Hide()
Dim docMgr As DocumentCollection = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager
Dim i As Integer = 0
For Each doc As Document In docMgr
